Much to the delight of rabid, froth-mouthed fans—and more than eight years of teasing on Acura’s part—a proper second-generation NSX sports car is on its way. The concept version debuts at the Detroit auto show in early January. (You can dive into the NSX 2.0’s decade-long gestation here, from its shifting engine placement to prototype spy photos to being repurposed as a race car. And those are just the tip of the iceberg.)

The first NSX was a technological tour de force when it arrived in 1990. The mid-engine sports car packed a dual-overhead-cam V-6 under an all-aluminum wrapper. The engine made 270 hp, a staggering number for a six-cylinder engine at the time. For all that, it was the car’s handling that was the most impressive—piloting an NSX is like having the controls hard-wired to your gray matter.

Acura has decided that the new NSX will again use a mid-engine layout and that it will follow the first car’s general philosophy: The second-gen model will be relatively lightweight, efficient, and make use of lots of new technology.

The company is still quiet about powertrain specifics, but we can offer some educated speculation. The engine will again be a V-6, but this time the gasoline engine will play a role in an ensemble hybrid-electric drivetrain. One or more electric motors likely will power the front wheels, and translation services between the gasoline engine and the tarmac will probably be provided by Honda’s new seven-speed dual-clutch gearbox. If this all sounds familiar, it’s because you read our own Mike Austin’s piece on Acura’s new hybrid AWD system. The impression we have is that the NSX’s powertrain will be inspired by the front-engine system Austin recently sampled in an Accord.

Styling-wise, the NSX concept we saw isn’t terribly far off from the sports car that Tony Stark (that’s Iron Man’s civilian name—or “Robert Downey, Jr.” if you want to get technical about it) drives in the upcoming Avengers movie. Proportions are similar to those of the original NSX: There’s a short, low hood, a relatively big canopy over the cabin, and a low, wide rear end. (The original car is pictured above—Acura hasn’t released official images of the concept yet.) This one’s also got side scoops to feed air to the engine.

When the car is unveiled at the Detroit show, Acura’s spokespeople are going to say this is a concept only. They may even say a decision is still yet to be made. But we hear it’s already received a green light for production, and will arrive sometime in 2012 or early 2013. It won’t be cheap, but Acura has no intention of approaching Lexus LFA pricing, either. We’d guess on a sticker in the $90,000-to-$130,000 range.
